How the Fed's rate moves reach your savings account

Every few weeks the financial news reports that the Federal Reserve has raised, held, or cut interest rates — and a little while later, the yield on your savings account moves in the same direction. Those two events are connected, but not as directly as most people assume. Understanding the chain in between explains why your rate lags the headline, why it doesn't move by the full amount, and why the bank down the street and an online bank can pay wildly different yields off the same Fed decision.

What the Fed actually sets

The Federal Reserve does not set the rate on your savings account. What its policy committee — the FOMC — sets is a target range for the federal funds rate: the interest banks charge one another for lending reserves overnight. Per the Federal Reserve, it steers the actual funds rate into that target range using its policy tools. That's the lever. Everything else — mortgage rates, credit-card APRs, and savings yields — responds to it indirectly.

The chain from a Fed meeting to your interest

Here's how a decision in Washington reaches your monthly statement:

1. The FOMC changes the target range. Say it raises rates.
2. Banks' own earning rate rises. Banks can now earn more on their safest, most liquid holdings — reserves and short-term Treasurys — because those track the funds rate closely.
3. Deposits become more valuable to banks — eventually. Your deposit is funding the bank lends and invests. When banks can earn more on that money, the money you deposit is worth more to them, which gives them room to pay you more to keep it.
4. Each bank decides how much to pass along, and when. This is the crucial, discretionary step. There's no rule forcing a bank to raise your savings rate at all, let alone by the full amount or on any timeline.

That fourth step is where the neat theory meets messy reality.

"Deposit beta": why your bank might barely move

Economists call the share of a rate change a bank passes to depositors its deposit beta. A bank that passes along most of an increase has a high beta; one that keeps the increase for itself has a low one. The pattern is consistent enough to plan around:

• Large banks with huge, sticky deposit bases often have low betas. They already have more deposits than they need, so they have little reason to compete on rate — savings yields at the biggest banks can stay near the floor even after several Fed hikes.
• Online banks and many credit unions tend to have high betas. They compete for deposits nationally, so they raise savings rates faster and further to attract cash. That competition is why online high-yield savings accounts routinely pay many times what a big-bank savings account does.

Same Fed decision, very different outcome for the saver — decided entirely by which bank holds the money.

Up slowly, down quickly

There's an asymmetry worth bracing for. Because most savings yields are variable, banks tend to raise them slowly when the Fed hikes but cut them promptly when the Fed eases — funding costs fall, and there's little competitive reason to keep paying the old rate. For a saver, that means:

• Don't assume a great rate is permanent; a variable yield can drop the week after a Fed cut.
• If you want to lock today's rate against a coming cut, a fixed-rate CD or a CD ladder is the tool — its rate is set for the whole term regardless of what the Fed does next.

The rate environment, described honestly

Rather than quote a number that's stale by the time you read it, the right frame is directional. When the Fed raised its benchmark sharply in 2022–2023 to fight inflation, competitive online savings yields climbed to their highest levels in well over a decade; when the Fed later began easing, those same variable yields drifted back down. The specific figure on any given day belongs to a dated source, not a blog post — the FDIC's monthly national deposit averages publish the current benchmark, and each competitive account posts its own rate with an "as of" date. Read those for the live number; use the chain above to understand why it is what it is.

What to do with this

1. Judge your bank by its behavior, not the Fed's. If your savings rate barely moved when rates rose, that's a low-beta bank telling you where its priorities are.
2. Compare against a dated benchmark. Hold your rate up to the FDIC national average and current high-yield savings offers, each with its date. A rate that's a small fraction of the competitive number is a standing invitation to switch.
3. Match the tool to the horizon. Variable savings for money you may need soon; a fixed CD to lock a rate for money you won't.
4. Re-check after big Fed moves. A meeting that changes the target range is your cue to confirm your rate is still competitive — up or down.

You can't control what the Fed does, but you fully control which bank captures it for you. Start with the savings explainer, see the regulator and credit-union landscape on a state page, and compare accounts against one published standard so a Fed decision actually shows up in your interest, not just the headlines.
